I guess it's different for me because unlike many here I've never read the comic books so I have no pre-existing love for the characters. For me all the knowledge of the characters comes from the movies.

So from my point of view, Storm is just a bland character played by a bland actress. I can't say I feel any enthusiasm about her possible return, at least this version of the character. If they can re-cast and re-invent her, say as a reboot or a younger version, that's of course a different story.

That's a criticism of the movies, not the character.

If the films made her bland, that's down to the writing/directing and possibly casting.
